hive-vault
Your AI coding assistant forgets everything between sessions. Hive fixes that.
Hive is an MCP server that connects your AI assistant to an Obsidian vault. Instead of loading everything upfront, it queries only what's needed — on demand.
| Metric | Without Hive | With Hive |
|---|---|---|
| Context loaded per session | ~800 lines (static) | ~50 lines (on demand) |
| Token cost for context | 100% every session | 0.6% for five project-context queries (real vault, 493K tokens) |
| Knowledge retained between sessions | 0% | 100% (in vault) |
Only the token-cost row is a measurement (5 project-context queries on a real 493K-token vault; method and numbers in the benchmarks). The line counts and the retention row describe how the two setups work; they are not measured.
Quick Start
Hive runs without a vault — vault tools return a friendly error until VAULT_PATH is set, so you can install first and configure later.
# Minimal — uses default vault path ~/Projects/knowledge
claude mcp add -s user hive -- uvx --upgrade hive-vault
# With a custom vault path
claude mcp add -s user hive -e VAULT_PATH=$HOME/path/to/vault -- uvx --upgrade hive-vault
# Gemini CLI
gemini mcp add -s user -e VAULT_PATH=$HOME/path/to/vault hive-vault uvx -- --upgrade hive-vault
